REF620E_F NBFNAAAANDA1BNN1XF 

The REF620 is the most powerful, advanced and simplest feeder protection relay in its class, perfectly offering time and
instantaneous overcurrent, negative sequence overcurrent,
phase step distance, phase discontinuity, breaker failure, thermal overload, and voltage metering and protection. The relay
also features high impedance fault (HIZ) and sensitive earth
fault (SEF) protection for grounded and ungrounded distribution systems. Also, the relay incorporates a flexible three-phase
multi-shot auto-reclose function for automatic feeder restoration in temporary faults on overhead lines.
Enhanced with safety options, the relay offers a three-channel arc-fault detection system for supervision of the switchgear. The
REF620 also integrates basic control functionality, which facilitates the control of up to 2 circuit breakers via the relay’s front
panel human machine interface (HMI) or remote control system.
To protect the relay from unauthorized access and to maintain the integrity of information, the relay has been provided with a
four-level, role-based user authentication system, with individual passwords for the viewer, operator, engineer, and administrator
levels. The access control system applies to the front panel HMI, embedded web browser based HMI, and the PCM600, Protection and Control IED Manager.
